Character Editor

[SpiderPig]

 I wonder if anyone here has any clues as to how most games achieve a character editor?

As a test I scale the bone but this isn't the result that's needed.  I'm thinking a float or two should be attached to each bone and the vertex shader can handle the scaling of the associated vertices around said bone.  I wonder if this can be achieved in Ultra yet...

auto model = character_viewer->GetCharacter();
auto value = 0.5f * (float)slider_head_height->GetValue();

auto head_bone = model->skeleton->FindBone("Head");
head_bone->SetScale(0.5f + value);

Nice start !

Thanks   In GUI alone Ultra is so much faster and more flexible than Leadwerks.  In Leadwerks rendering a character like this with a 2nd camera dropped the FPS from 200 to about 50 If I remember correctly.

And now I can manipulate the vertices around a single bone with the shaders.  Here only the toe bone is raised by 1.0f.  It's just a matter of finding a way to identify the bone I want to edit and deciding on the right way to edit them.  It will probably be something like expanding the vertices away from the bone's axis within a certain range and reducing that range to 0 as it nears either end of the bone.  Tomorrow I'll see what I can do.

3 Hours later and I can edit the vertices around the head bone.   Now I just need to work out how to change the shape smoothly and more naturally.

Still needs refining but the general inner workings are there.

Use shape keys, and i also think you can scale body parts by bones.
